A subgroup H of a p-group G is n-uniserial if for each i = 1,...,n, th
ere is a unique subgroup K-i such that H less than or equal to K-i and
\K-i:H\ = p(i). In case the subgroups of G containing H form a chain
we say that H is uniserially embedded in G. We prove that if p is odd
and that K is a 2-uniserial subgroup of order p in the p-group G. Then
K is uniserially embedded in G. We also show that for p > 3, if K is
a 2-uniserial cyclic subgroup of the p-group G, then K is uniserially
embedded in G. We prove the following two theorems: (1) Let A be a sof
t subgroup of index greater than p. Let N-1 = N-G(A) and R = G'Z(N-1).
Then the A-invariant subgroups of R containing Z(N-1) form a chain. (
2) Suppose that the p-group G has a uniserially embedded subgroup P of
order p. Then either G has a cyclic subgroup of index p or is of maxi
mal class (coclass 1).
